TECHNICAL FIELD

The present invention relates generally to footwear and moreparticularly to a shoe that has been adapted to improve a walker's powerposture and comfort. This is accomplished by a unique shape & structureof footwear arrangement, which optimizes the use of all muscles of lowerlimbs and increases the power of the walker, present inventive shoeadopts to the shape of the foot and supports the foot in all stages ofnormal walking, provides shoe spring or rebound cushioning. Although theshoe provides benefits which extend to all forms of footwear includingsports shoes, it has proven especially effective for use by people whowalk for exercise and or competition, and is described in the context ofrace walking below.

BACKGROUND OF THE INVENTION

Locomotion or walking is an important and basic function of humans. Ourlife depends on walking, Walking is essential in providing the basicnecessities of life, ‘Movement is life and life is movement’ andmovement is necessary to all living beings, walking has evolved overmillions of years. Human walking is an advanced form of walking of allliving creatures. Each and every muscle, bones are interlinked,developed and evolved to the needs of varied movements of the body,perfected and evolved to the present state, thus human walking is ahighly evolved essential organ system, all other organs of our body likeheart, liver, kidney, digestive organs are built around the walkingorgan, “life means walking, walking means life”, due to the faulty andunscientific foot wear presently used, normal walking is suppressed,this causes disuse of muscles and humans are suffering from life stylediseases, hence foot wear is not just a protective device of the footbut also a health device, foot is the gate way of individual's health.

Foot wear has been designed as protective device to the foot, manyinventions have been taken place in the field of foot wear yet so far nofoot wear has been designed to suit the normal walking style of humans.Human's foot is flat, yet normal walking is not flat it takes manyshapes with each step but our present foot wear is flat, sole of thepresent foot wear is hard and inflexible, foot in natural walking isflexible and changes its shape, hence present foot wear do not promotenormal walking due to this rigidity and this defect in the present footwear leads to life style diseases like obesity, cardiac diseases,osteoporosis arthritis of knee, spondylosis, backache, ankle fractures,hip fractures and other diseases, It is evident that lack of properwalking techniques and exercise are the main reason for the advent ofthese life style diseases.

Normal walking has heel strike, foot flat, heel off and toe off stages.Modern foot wear with its hard rigid soles do not allow so manymovements of the foot, this causes disuse atrophy of various muscles ofthe leg, back and other parts of the body, in effect our body graduallyadjusts to the foot wear, instead of foot wear adjusting to our foot, weare left with one movement of the foot that is foot flat stage, Thismakes a chain of reactions in the body, the muscles gets disuse, bulk ofthe muscles decreases, body falls to this trap and succumbs to modernlife style diseases as a consequence to the use of badly designed rigidsoled foot wear.

In recent years to overcome the modern life style diseases there hasbeen an explosion in the physical fitness industry, and correspondingly,in the desire for better equipment which improves an individual'sperformance of activities which promote good health, perfect walking isan area which requires a particular importance which improve physicalcondition without unduly taxing an individual's joints, walking havethus popularized and have developed into competition sports such asperformance walking or race walking, the sport serves as an increasinglypopular form of exercise and recreation, attracting persons of differinglevels of skill and physical ability, the fitness industry, however, hasbeen slow in recognizing this trend, and has yet to develop anacceptable walking shoe, walkers have thus been forced to use therunning shoes, shoes designed to accommodate a high impact activitywhich requires very different foot posture, stride technique, impactabsorption, and overall shoe use from that of performance walking orrace walking.

Walking technique consists of series of steps, where each stepconstitutes a cycle in which the walker shifts from a single supportphase to a double support phase and then back to the single supportphase. In the single support phase the walker's entire weight isbalanced on one foot, the other foot being moved forward so as to movethe walker into the double support phase. In the double support phase,the walker's weight is balanced between a leading and a trailing foot,the trailing foot is used to push the walker forward so as to againenter the single support phase, and begin the cycle anew, theaforementioned “push-off” begins during the single support phase whenthe walker's center of gravity passes over the supporting foot. Thewalker, at all times, has at least one foot in contact with the ground,reducing the impact associated with each step, and resulting in anoverall lower impact exercise routine.

With each step in the stride phase, the human's foot lands on the heelor heel strike phase, and moves forward to a planted position or footflat position with the heel and a ball of the foot supported from below.The ball of the foot acts as a fulcrum, the walker's foot pivotingforward about the fulcrum as the walker's center of gravity passes thereover, the foot then moves forward to heel off and toe off stages, Thisstage accommodates push-off by the walker's toes, the walker's push-offwith the trailing foot to assist the leading foot to plant so as toprovide the walker with longer stride and stable support.

In conventional shoes the sole of the shoes is flat, in some shoe thewearer's heel is elevated relative to the toes and the ball of the footpreventing the movement of the foot and in all the shoes the sole willbe rigid, hard and inflexible and flat when the foot is planted, thisarrangement of the shoes does not allow double support and causes thedisuse of leg, thigh & hips muscles and decreases in size this leads toimproper walking posture, which can lead to injury, bad posture detractsand decreases the wearer's walking power and walking speed, the wearerwill tend to stand with a body reclined slightly so as to maintainbalance, stand on the front of the foot rather than back of the footresults in an unhealthy posture and increases the likelihood of injuryto the walker's lower torso, conventional shoes also detract fromwalking efficiency because it is necessarily provided a sole with anundersurface which is generally planar, rigid and inflexible from theshoe's heel to the tip of its toe, however, during fast walking, planarshoes may be uncomfortable and does not confirm to the shape of the footalong the various stages of walking, most of the times this deters thefoot movement, reduces the use of calf muscle and hamstring muscle andin turn reduces the bulk of the calf muscles, hamstrings muscles andgluteus muscles.

SUMMARY OF INVENTION

The problems explained are overcome by the present inventive design. Thedevice according to the invention for perfect Gait shoe 1 hereinaftercalled Perfect Gait Shoe 1, comprises an upper shoe 2 and a sole 3, theupper shoe 2 is used for the reliable fixing of the walking device 1 tothe foot, this can take place by means of straps, such as are used forsandals, laces as are used in the case of beach shoes or an entire uppershoe made from leather or a textile material, what is important is thatthrough said upper shoes 2 the foot is firmly and comfortably connectedto the midsole 10.
